First of all there’s not that many of them in reality, and the ones that are usually don’t last for any length of time... With a few exceptions.
As of 2017 there were about 550,000 same sex married couples. And their divorce rates are roughly the same as straight couples.
The single most striking thing to remember about same sex marriages is how.....unremarkable they are. They're just marriages. Folks raising families, living their lives, stepping on legos, attending parent teacher conferences, going on vacations, visiting family, with some getting divorced.
Just folks doing what folks do. Which is also boringly sane.
